摘　　要：通过模拟支柱绝缘子和穿墙套管的沿面放电模型,对电极结构、极间距离、表面电导率以及所加电压的极性等对沿面闪络电压的影响进行了试验研究,并分析了不同模型闪络特性差别的原因。The surface discharge models that can simulate the electrode configuration of the wall bushing and the post-type insulator are established.With this model the influence of the electrode configuration,interpolar distance,surface conductivity and the polarity of the applied voltage on the flashover voltage along the surface is investigated.The reason which causes the differences of the flashover characteristics between two electrodes is analyzed.
